Fran, I don't know how selective the malware might be. It could certainly be a purely random thing and I happened to get caught in the crosshairs of this particular phishing scheme. I have Trend Micro regularly scheduled and constant Internet firewall scanning enabled as my virus and malware protection so I just had Trend scan for malware as the screens started poping. I also went to Microsoft's Windows Security Center and had my computer scanned and update my security center malware removal software. Trend Micro has a free onsite scanning feature as I'm sure many anti-virus packages do here:
